Spirent TestCenter: Does the dropped stream results always report the worst case of all streams?

Environment/Versions
  • Will Spirent TestCenter always report worst case of all the streams when a DRV is created in a scenario where number of streams is more than 2k?
Answer
  • Verified behavior with the following tests:
    • Sent traffic from port 3/5 (40,000 streams)
    • 4 Ports Receiving on 3/6, 3/7, 8/5, 8/6 each receiving 10,000 streams
      • Breaking link on 8/6 for 5 seconds and see port 8/6 streams displayed in the Dropped Stream Results.
        • Results = 2000 displayed / 10,000 total
      • Breaking link on 8/5 for 10 seconds and then see port 8/7 streams sorted at the top (more drops than 8/6)
        • Results = 2000 displayed / 20,000 total
      • Breaking link on 3/7 for 15 seconds and then see port 3/7 streams sorted at the top (more drops than 8/5)
        • Results = 2000 displayed / 30,000 total
      • Breaking link on 3/6 for 20 seconds and then see port 3/6 streams sorted at the top (more drops than 3/7)
        • Results = 2000 displayed / 40,000 total
  • So the streams with the most drops will show up at the top. See snap shot of above results.
